Description
Technical Field
The invention relates to the technical field of computer multimedia information processing, in particular to a pixel position distribution optimization method for a panoramic image or video.
Background
Panoramic video is a representation of Virtual Reality (VR) that presents a 720 ° scene to the viewer, giving the viewer an immersive viewing experience. At present, a panoramic video is usually in a spherical projection mode. When the spherical display equipment is available, the panoramic video adopting the spherical projection mode can be directly played on the spherical display equipment. When there is no spherical display device, only a flat display device, a compromise playing method may be used, i.e. it is assumed that the flat display device is a window through which the user can only see a part of the panoramic view. The user can control the view angle of the user in the panoramic view field by means of mouse dragging and the like.
On the other hand, panoramic video is still represented and stored in a rectangular plane mode, namely, a spherical surface is mapped into a rectangular plane when the panoramic video is manufactured. After the mapping from "sphere → moment" the image appears more severely distorted, however this distortion is desirable because it automatically disappears if the video is played on a sphere player. If the video is played through a "view-window panoramic player", the player will project a sub-area of the panoramic video onto the viewing plane according to the viewing angle selected by the user, which is called inverse distortion. After transformation, the density of the pixel points near the two poles of the spherical surface is higher, and the density of the pixel points near the equator of the spherical surface is lower. This situation is easy to understand because the pixel points at the upper edge of the rectangular plane are all mapped near the spherical north pole, and the pixel points at the lower edge of the rectangular plane are all mapped near the spherical south pole, which results in a high density of pixel points at the spherical poles and a low density of pixel points near the spherical equator. The unbalanced distribution of the pixel points on the spherical surface is just deviated from the viewing requirement of the spherical panoramic video, and the reason is that in most cases, users mainly view scenery near the equator in the spherical surface, the scenery located at the north pole of the spherical surface is generally sky or roof, and the scenery located at the south pole of the spherical surface is generally ground. Therefore, the imbalance of the distribution of the effective pixels causes less pixel points in the area which needs to be viewed by the user, and more pixel points in the area which does not need to be viewed by the user. For this reason, we propose a pixel position distribution optimization method of a panoramic image or video to be put into use to solve the above-mentioned problems.
